Abstract

An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, and the artificial flagstone has no rotational symmetry when rotated about a central axis.

Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. An artificial flagstone for use in combination with other ones of the artificial flagstone for covering a surface with a natural random look, the flagstone comprising:
 at least first, second, and third consecutive vertices; 
 a first pair of first and second sides extending radially from the first vertex; and 
 a second pair of third and fourth sides extending radially from the third vertex; 
 wherein the sides of at least one of the first pair of sides and the second pair of sides are respectively rotational images of each other and have at least one split deviation along their length; 
 whereby in use in combination with the other ones of the artificial flagstone, each one of the sides is matingly engageable with the sides of an equivalent pair of sides of a neighboring flagstone. 
 
     
     
       2. The flagstone as claimed in  claim 1 , wherein the sides of the first pair of sides are approximately half a length of the sides of the second pair of sides. 
     
     
       3. The flagstone as claimed in  claim 1 , wherein each of the sides has a chiseled upper edge. 
     
     
       4. The flagstone as claimed in  claim 1 , further comprising a top face comprising a plurality of joints dividing the top face into smaller top sections. 
     
     
       5. The flagstone as claimed in  claim 4 , wherein the top face comprises a texture that imitates a natural flagstone. 
     
     
       6. The flagstone as claimed in  claim 4 , wherein the flagstone further comprises a bottom face positioned below the top face, wherein the top face has a contour line generally similar to the bottom face and a surface area smaller than a surface area of the bottom face because of spaces created in the top face by the plurality of joints. 
     
     
       7. The flagstone as claimed in  claim 1 , wherein the at least one split deviation comprises a first generally straight segment, followed by the split deviation and a second generally straight segment. 
     
     
       8. The flagstone as claimed in  claim 1 , wherein the sides of each of the first pair of sides and the second pair of sides have at least one split deviation along their length. 
     
     
       9. The flagstone as claimed in  claim 1 , wherein the second side and the third side are rotationally spaced from each other by an angle of approximately 135°. 
     
     
       10. The flagstone as claimed in  claim 1 , wherein all of the pairs of sides have distinctive markers guiding a lay out of a plurality of the flagstone on a surface. 
     
     
       11. The flagstone as claimed in  claim 10 , wherein the distinctive markers are located at the vertices. 
     
     
       12. The flagstone as claimed in  claim 11 , wherein the distinctive markers consist of thin plate-shaped members protruding from the vertices.
